Lac Blanc is the starting point for various trails leading to the Gazon du Faing and the Col du Bonhomme.
Lac Blanc is a glacial lake located in the Vosges mountains of France, situated at an elevation of 1,055 meters. It is distinguished by its deep turquoise waters and the dramatic 200-meter-high granite cliff, the Rocher Hans, which overlooks the shoreline. The lake basin was carved by glacial activity during the Würm glaciation. It is part of the Vosges du Nord regional landscape and remains a popular destination for hikers exploring the ridgeline trails. The site is connected to the nearby Lac Noir via a hydroelectric pumped-storage power station system. The surrounding environment consists of spruce forests and steep mountain slopes. It serves as a primary hub for the GR5 trail system in the region.
